If you know exactly when you ovulated based off of the ovulation tests you took, can you base your due date off from that? Or does it have to certainly be from your first day of your last menstrual period?

Re

I ovulated on Sept 1 which would make my due date May 25, 2022 but, based of my LMP my due date would be May 22, 2022. Which is only a shy of 3 days... I'm hoping for my due date to be May 25, 2022 because I'm hoping for a Gemini baby but, based off my LMP its May 22, 2022😞 Is it possible to just go by the day I ovulated?
